Abstract
Color Doppler processing is one of the most important utility in the ultrasound imaging systems. Color Doppler imaging is mainly used to observe the blood flow in the region of interest. The desired blood signal will be greatly affected by the clutter and speckle noises, and it is the major design issues to eliminate these two kinds of noises effectively. In this work, we proposed a (1) joint-decision clutter filter and (2) motion-tracking adaptive persistence for effectively eliminating the clutter and speckle noises, respectively. The proposed two filters have individually 2∼3 dB better performance than the referenced algorithms, and the proposed adaptive clutter filter and persistence can also work together in the same system to obtain even better performances. ©2010 IEEE.
